<p>I always recommend 20 to 40 minutes per day on SAT prep. Yes, 20 minutes is a short amount of time. BUT, most of what you learn in those 20 minutes will be retained. If you do 40 minutes without break, most of the middle will be “lost.” The average human brain retains the first few minutes and the last few minutes of what you study.</p>
<p>If you’re studying over a period of several months, and studying efficiently, that short amount of time each day adds up to A LOT of effective studying.</p>
